Until that time though, Mattison is back in charge and at least according to the players, there isn't exactly a big difference.

"I've had Mattison for two years so going back to Mattison really wasn't a big issue for us cause that's who we were used to the last two years," Charlton said.

"Durkin was a great guy for us, he did a lot for us and brought a different mindset to us and we had a great defense this year."

Michigan's defense was very consistent, especially to start the 2015 season, at one point pitching three consecutive shut outs.

In the final test of the season though, the Wolverines allowed 42-points in a blowout loss to Ohio State in Ann Arbor.

"We corrected those (mistakes) that next week, the next following week," Charlton said. "We watched film to see what we did bad. We knew we had some things that we could've done a lot better that we didn't do.

"After watching the game and watching the corrections we knew it was a lot of mistakes we could fix and we did that throughout the whole bowl practice."

Gearing up for a Florida offense that features offensive coordinator Doug Nussmeier, who spent 2014 guiding Michigan's offense, Charlton knows the challenge will be stiff.

"They have a lot of explosive players," he said. "They get a lot of players with the ball in their hands, they can do a lot with it.

"They've got a running back that's very explosive, the quarterback is good on his feet too and they've got a lot of explosive receivers."
